Answer:
It really depends - in general every data structure has its use.
Explanation:
Furthermore, traversing the list will be inefficient because the data items are not contiguous in memory, forcing the CPU to jump all over the RAM memory causing further slowdown.
You can do something like this :
Scanner sc = new Scanner(System.in);
int[] nums = new int[4];
for(int i = 0; i < nums.length; i++) {
System.out.println("Enter next number: ");
nums[i] = sc.nextInt();
The answer would be slide
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Betty is developing a machine learning algorithm that looks at a vast amount of data that is collected over 100 years, and She also wants to check the relationship among variables such as humidity, temperature, and rainfall in the given data.
So, the correct answer to this question is b. She is developing an association machine learning algorithm.
Because the association tells the relationship between variables. She used the association to find the relationship among variables such as humidity, temperature, and rainfall.
While the other options are not correct because:
Regression is used to find out the cause and effect relationship between dependent and independent variables. Big data is the biggest field of data analysis, so this option does not best suit this context. Classification is used to classify data, or organizing data into their related group. While clustering is the task of dividing the population into a number of groups such that populations in the same groups are more similar to other populations in the same group than those in other groups. so these are all incorrect options to this question except the "b" option i.e association.
Answer:
only D.
Explanation:
A is false because you can only declare it once, then call it multiple times.
B is false does not affect the number of commands. You can expect that the function commands are run multiple times.
C is false because the amount of work the program has to do does not change.
D is spot on.
